It is best to put the freshly roasted coffee beans in a one-way valve bag, because they are still venting. After 48 hours, they can be placed in a glass sealed jar for preservation.
If there is no glass jar, when the coffee beans in the bag or sealed jar are opened, after use, try to exhaust the remaining air in the container as much as possible to reduce the excessive contact between the roasted coffee beans and the air. Or pack them into small bags and squeeze out the air for storage.
